BARR'EL-ADJUSTING APPARATUS.

Specification of Letters Patent.

Patented Apr. 2'?, 1915- Application filed August 4, 1910, Serial No. 575,558. Renewed September 2, 1914. Serial No. 859,919.

T0 all fui/1,0m 'it may concern Be it known that I, PAUL ROMBERG, a subject of the King of Saxony, residing at Leipzig, in Germany, have invented a certain new and useful Improvement in Barrel- Adjusting Apparatus, of which the following is a specification.

This invention relates to barrel-adjusting apparatus for use in, or in conjunction with, machinery for automatically cleaning bar rels, the function of the adjusting apparatus being to adjust or center the barrels so that the bung-holes are positioned to receive streams of fluid (water, pitch, steam, etc.) discharged from nozzles toward which .the barrels are conveyed from the adjusting mechanism.

The conveyer and cleaning mechanism do not form part of the present invention.

The adjusting device comprises a socalled bungehole finder, z'. e. a pin adapted to tem` porarily engage the barrel by entering the bung-hole, means for revolving the. barrel, and movable barrel-guides connected so as to have similar opposite movements by which the revolving barrel is centered so that the finder enters the bung-hole.

The essential novel feature of the invention consists in the fact that the adjusting mechanism is opened or adjusted by the effect of the weight of the barrel in the approach of the barrel to the barrel revolving rollers. For this purpose the barrel-guides are so arranged that in their normal position, they are lying in the path of the arriving barrel, so that they must be correspondingly moved, before the barrel is mounted upon thebarrel revolving rollers. Therefore, it requires no special actuating means for said movement of the adjusting mechanism, such as is required in all similar devices hitherto known. In addition to essentially simplifying the mechanism, this arrangement has the advantage that the adjusting of the barrel begins d1- rectly upon its arrival on the barrel revolving rollers, because the initiation ofthe effect is not dependent upon any mechanical actuating means. i

Two constructions embodying this 1mprovement are shown in the accompanying drawings.

Figure 1 is an elevation .of one construction, showing the barrel-guides thrust apart by a barrel centered between them, and Fig. 2 a similar view, showing the barrel guides as positioned prior to arrival of a barrel.

, greater force than small barrels.

Fig. 3 is a side view of the other construction, and Fig. 4 a plan view thereof.

Referring in the first place to Figs. l and 2, the barrelguides are rollers 42 mounted upon bell cranks 40 pivoted at 39. The bell cranks are engaged with each other at the bottom by means of toothed segments 41, soas to have similar movement whereby the guide rollers 42 are uniformly moved to and from the barrel revolving` rollers 3S rotated by means of gear from a shaft 5. There are two pairs of barrel revolving rollers 38, arranged one behind the other so that only one is visible in the drawing, and the bunghole finder 45 is centrally arranged between the two pairs. Weighted levers 44 pivoted at 43 carry rollers 400 bearing against the bell cranks, and tend to thrust the bell cranks and therefore the guide rollers 42 inward. The weighted levers 44 are disposed so that the thrust decreases as the guide rollers 42 move inward, the result being that large barrels are acted on with Before the arrival of the barrel, the barrel guides are in normal position, as shown in Fig. 2.

en a barrel arrives, z'. e. when it is lowered between the barrel guides, it abuts against them, or one of them, and thrusts them apart. After the barrel has been mounted upon the barrel revolving rollers 38, the simultaneous and similar opposite movements of the barrel guides insure that the barrel becomes accurately centered, when the barrel has been unsymmetrically mounted upon the barrel revolving rollers 38. The distance between the upper ends of the barrel guides is greater than the length of any barrel which is to be treated, so that barrels of any size are conveyed between the barrel guides though they arrive unsymmetrically, and they must thrust the said barrelguides apart.

In the construction shown in Figs. 3 and 4, the guide rollers 421 are mounted upon double armed levers 401 fixed to a loose spindle 391. The guide rollers 421 have the bung-hole iinder 451 centrally between them, and diverge symmetrically upward. The levers 401 are weighted by weights 441 by which the guide rollers are normally held in such position that a barrel lowered between them abuts against them before reaching the finder 451. The rollers then uniformly descend, and by their symmetry correct any deviation of the barrel from centricity relative to 'the lfinder 451, after the barrel has been mounted upon the barrel revolving rollers 381.

Springs may be substituted for weights as means whereby the guides 'are moved to normal position.

What I claim as my invention and desire to secure by Letters Patent of the United States is 1. In a barrel adjusting apparatus the combination of a barrel receiving device and adjusting guides symmetrically placed with regard to said device and'intersecting the side edges of the path of the barrel thereto.

2. In a barrel adjusting apparatus the combination with a barrel receiving device comprising barrel revolving rollers and means for rotating them, of adjusting guide Copies of this patent may be obtained for rollersy located obliquely symmetrically with regard to the receiving device and movable to and from the same.

3. In a barrel adjusting apparatus the combination of a barrel receiving device and adjusting guide rollers similarly movs able to and from said device and intersecting the side edges of the path of the barrel thereto, said adjusting guide rollers being under tension tending to move said guide rollers toward one another.

4f. In a barrel adjusting apparatus the combination of a barrel receiving device and adjusting guide rollers similarly movable to and from said device and intersecting the Aside edges of the path of the barrel thereto, said adjusting guide rollers being under tension tending to move said guide rollers toward one another, the tension increasing as the distance between the guide rollers increases.

5. In a barrel adjusting apparatus the combination of a barrel receiving device and bell cranks carrying adjusting guide rollers similarly movable to and from said device and intersecting the side edges of the path of the barrel thereto, the bell cranks being connected so that their symmetry is maintained during said movement.

In witness whereof I have signed this speciiication in the presence of two witnesses.
